Answer: The hieght is 12.7 inches
Step-by-step explanation:
r=d/2
3.5/2=r
r=1.75
v=pir²h
122.5 =piR²h
122.5=pie1.75²h
The frist thing to solve for r sense exponents come before multiplication in bedmask
122.5 =pi3 .06g
so then it's pie times r
122.5=9.61 *h
122.5/9.61=h
12.7=h

Lily needs to order some new supplies for the restaurant where she works. The restaurant needs at least 420 spoons. There are currently 159 spoons. If each set on sale contains 6 spoons, write and solve an inequality which can be used to determine s, the number of sets of spoons Lily could buy for the restaurant to have enough spoons.
Answers
But they already have 159.
So they are missing 261.
The spoons on sale, are 6 spoons per set.
So you are gonna divide 261 by 6.
Which gives her 43.50 sets of spoons
But you have to round that up to 44 sets of spoons.

Answers
Answer:
y = 5/2x + 5
Step-by-step explanation:
To find the equation, you first need to find the slope. You can do this by subtracting the two y coordinates (the two last numbers) and using that as the numerator (the top number of the fraction), and then subtracting the two x coordinates (the two first numbers) and using that as the denominator (the bottom number of the fraction). You then have the fraction -5/-2, which can be changed to 5/2 because they are both negative numbers. That is your slope. You then need to find the y-intercept (where the line connects with the y-axis). To do this, you need to figure out what the y (the second number) is when the x (the first number) is 0. In this example, you can already see with the second set of coordinates that the y-intercept is 5 because the x is 0. When this is not easily shown, you can figure out the y-intercept with a table. Sorry if I made it sound too complicated :)

Answers
She uses 2 lemons to obtain 6 tablespoons of lemon juice.
16 tablespoons = 1 cup
1 tablespoon = 1/16 cup
6 tablespoons = 6/16 cup = 0.375 cups
Since ratio between lemon and sugar is 1:2
So amount of sugar required = 0.375 x 2=0.75 cups
Ratio between lemon and water is 1:8
So amount of water requires = 0.375 x 8= 3 cups
Therefore amount of lemon juice, sugar, and water required = 0.375 cups, 0.75 cups sugar and 3 cups respectively

Answer: 8,700
Step-by-step explanation:
lets say you have 500 animals, and you decide to get another 500, but you decide that you want an extra 500, and then your kid says that they want another 500 animals. You now have 2000 animals, but you also need 4000 chickens so you now have 6000 animals. Then you need 900 pounds of animal food, but 900 pounds is weird so you get an extra 100 to make your total 1000. But now you need 800 dogs so you now have 2800 animals.
4000 + (500 x 4) + 900 + 100 + 800 = 8,700

Game Profit ($)
1 −12.50
2 −10.15
3 18.65
4 25.90
5 45.75
Based on the average profit per game, how much total money can the club expect to earn by the end of the 10-game season?
__ dollar(s)
Answers
Answer:
First, we need to take the average of the numbers. So, we will add 12.50, 10.15, 18.65, 25.90, and 45.75, getting us 112.95. Then we need to divide this by 5 to get the average profit for each game, getting us the number 22.59. Then we add up the money already earned with 22.59*5 (getting us 112.95 + 112.95), which gives us the number $225.9.
Hope this helps!
The total profit by the end of the 10-game season is $225.9.
How to calculate the average?In order to calculate average, divide the total sum of the data to the total number of data. An average is a standard number for a given data whose value can both be more or less than it.
The given problem can be solved as follows,
The average profit for the five games can be calculated by summing the profits all the five games and then dividing it by 5 as below,
(12.50 + 10.15 + 18.65 + 25.90 + 45.75)/5 = 112.95/5 = 22.59
Now, the profit for 10 games is the average profit multiplied by 10.
22.59 × 10 = 225.9
Hence, the total money the club can expect to earn by the end of the 10-game season is $225.9.

Ravi wants to buy a new guitar that costs $129.99. He has $27, and decides to give music lessons to earn the rest of the money. Ravi decides to charge $22 per lesson. Which inequality would best help Ravi find m, the number of lessons he would need to give in order to buy the guitar?
Answers
Answer:
Step-by-step explanation:
A. 22m + 27 129.99
this is because ravi needs AT LEAST $129.99. (it could be = too if thats an option, but you said inequality so i think its this!!)
ravi already has $27, and he just needs to charge music lessons to get the rest, which is $22 per m (music lesson).
so, 27 + 22m ≥ 129.99!!

The descending numeric order of the laps was completed as 59, 58, 45, 0.875,0.833
What is descending order?Descending order is defined as when numbers (or other items) are arranged from the largest numbers to the least numbers, it is said to be in descending order.
Sara finished 45 laps, Jamie completed 58, Keenan completed 59, Maya completed 0.833, and Trey completed 0.875.
We have the given numbers as:
45, 58, 59, 0.833, 0.875
we have to determine the descending order of given numbers
Here the largest numbers to the least numbers, it is said to be in descending order.
⇒ 59 > 58 > 45 > 0.875 > 0.833
Hence, the descending numeric order of the laps completed:
Keenan completed 59 laps
Jamie completed 58 laps
Sara completed 45 laps
Trey completed 0.875 laps
Maya completed 0.833 laps

Expression for yAdding 4x to the first equation gives an expression for y:
6 +4x = y
SubstitutionThis can be substituted into the second equation:
-5x -(6 +4x) = 21
-9x -6 = 21 . . . . . simplify
-9x = 27 . . . . . . . add 6
x = -3 . . . . . . . . . divide by -9
6 +4(-3) = y . . . . . . . find y using the expression for y
